FIELD OF THE INVENTION

The present invention relates to slab edges. In particular, the present invention relates to balcony edges.

BACKGROUND OF THE INVENTION

Concrete slabs, such as those found on balconies, have limited lifespans. They are built according to specifications which should provide a decades long life span. Unfortunately, often as a result of environmental conditions, the balconies must be replaced within 8-12 years. The process of re-finishing is labour, resource and time intensive for those re-furnishing the balconies. The re-furnishers must:

-   -   set up scaffolding in order to access the balconies;     -   employ impact tools (e.g. jack hammers) to remove the damaged         balcony portions while at the same time preserving any existing         reinforcing bars within the slab structure; and     -   set up form work to pour re-finishing concrete.

Also this process often times significantly inconveniences the individuals who use the balconies. The noise and dust created is often intolerable. The dust generated can sometimes permanently damage personal possessions.

The remains a need for a system and method for finishing a slab edge which mitigates or obviates at least some of the above-presented problems.

DETAILED DESCRIPTION

Referring to FIG. 1( a), a cross-sectional view of a finished slab edge 10 is illustrated in accordance with an embodiment of the present invention. In a preferred embodiment, the slab edge 10 is a balcony edge. However, as will be apparent to those skilled in the art, the slab edge 10 may be any known concrete slab, such as a parking garage pad.

The finished slab edge 10 comprises a slab edge casing 11, which in turn comprises a face 13, the outside surface of which defines a finished slab edge 15 for an unfinished slab edge 17. The casing 11 also comprises a base 19, which extends from the casing face 13. The base 19 may be connectable to a slab face 21 adjacent the unfinished slab edge 17, as is illustrated in cross-section in FIG. 2( a). Alternately, the base 19 may register with the unfinished slab edge 17, as is illustrated in cross-section in FIG. 2( b). A registration plate 63 may be employed to aid in registering the base 19 with the unfinished slab edge 17. The plate 63 is preferably composed of the polymer, such as a glass fibre reinforced polymer or a GFRP as is known in the art. The plate 63 may be connected to the base 19 and unfinished slab edge 17 by any suitable means known in the art.

Referring again to FIG. 1( a), the face 13 and base 19 have respective inside surfaces 23, which define a form into which concrete is poured and allowed to cure.

The casing 11 also preferably comprises a plurality of ribs 39, which extend from the inside surfaces 23. The ribs 39, which are preferably formed along with the casing 11 as a unitary structure, aid in securing the concrete in position within the form.

The finished slab edge 10 also comprises a reinforcing element 31, which is securable to the unfinished slab edge 17. The reinforcing element 31, when secured to the unfinished slab edge 17, extends from the unfinished slab edge 17 to a terminal end, which ends at a point that corresponds to at least the finished slab edge 15. Preferably, the reinforcing element 31 is securable within a hole (not shown) that has been drilled into the unfinished slab edge 17.

In a first embodiment, the reinforcing element 31 comprises an anchor bolt 33 that is securable within the hole; a rod 35, which extends from the anchor bolt 33 to the terminal anchor point; and, a coupler 37, which connects the anchor bolt 33 to the rod 35. Preferably, the rod 35 is a threaded rod, a portion of which extends beyond the casing 11. The rod 35 is preferably composed of a steel, such as stainless steel. Alternately, the rod 35 is composed of a plastic. As will be apparent, the rod 35 may comprise any suitable material that is substantially inert to the environmental conditions of the installation.

Referring now to FIG. 1( b), a cross-sectional view of the finished slab edge 10 in accordance with a second embodiment is illustrated. The reinforcing element 31 may alternately comprise an extended rod 77, which extends from the hole to the terminal anchor point. The extended rod 77 is a one-piece threaded rod, a portion of which extends beyond the casing 11. The rod 77 is preferably composed of a steel, such as stainless steel. Alternately, the rod 77 is composed of a plastic. As will be apparent, the rod may comprise any suitable material that is substantially inert to the environmental conditions of the installation. The extended rod 77 is preferably held in place within the hole with the use of a suitable adhesive, such as an epoxy glue or cement.

Referring to FIGS. 1( a) and 1(b), the extending portions of the respective rods 35, 77 are configured to receive the lock 47. Preferably, the lock 47 is a lock nut or knob.

In a preferred embodiment, the lock 47 is also composed of a polymer that is resistant to the deteriorating effects of the environmental conditions of the slab installation. For example, the lock 47 may be composed to a suitable plastic.

Referring again to FIG. 1( a), the casing 11 is preferably composed of a polymer, such as a glass-fibre reinforced polymer (GFRP) or a polyvinyl chloride (PVC), as is known in the art.

The face 13 of the casing 11 preferably has a length (l) corresponding to the height of the slab edge 10. In order to accommodate varying slab heights, the face 13 may be cut to the required height at any point during the installation process. Alternately, and preferably, the casing face 13 comprises a first face portion 41 and a second face portion 43. The first and second portions (41, 43) are positionable with respect to each other and securable to each other at a position having a face length (l) corresponding to the slab height. Preferably, the first and second portions (41, 43) are slidably moveable with respect to each other. For example, referring to FIG. 3, a front view of the first and second portions (41, 43) is illustrated. The first portion 41 comprises at least one, and preferably a plurality, of guide channels 45, the positioning of which corresponds to the point at which the portion of the rod 35 (or rod 77 as is illustrated in FIG. 1( b)) of the reinforcing element 31 extends beyond the casing face 13. The extending portion of the rod 35 is then engaged by a lock 47, thereby securing the first and second casing portions (41, 43) to each other. The lock 47 preferably works in combination with a pair of washers 83 and nut 81. The guide channels 45 may be formed at any point during the manufacture and installation process. For example, channel 45 may be pre-positioned during the manufacturing process. Alternately and preferably, the channel 45 is positioned and formed on-site during the installation process.

The face 13 also preferably comprises a reinforcing element mount 25. Alternately, the base 19 comprises the reinforcing element mount 25, not shown.

The reinforcing element mount 25 may comprise a passage extending through the face 13, the rod 35 (or rod 77 as is illustrated in FIG. 1( b)) passing through the passage. The reinforcing element mount 25 may further comprise related mounting accessories, such as the nut 81, washers 83 and lock 47. The reinforcing element mount 25 may be formed at any point during the manufacture and installation process. For example, the mount 25 may be pre-positioned during the manufacturing process. Alternately and preferably, the mount is positioned and applied on-site during the installation process.

The slab edge casing 11 further comprises a base mount 27, which is configured to receive securing means for securing the base 19 to the adjacent slab face 21. In a preferred embodiment, the base mount 27 is a passage extending through the base 19 and the securing means is a screw 29 (preferably a self tapping screw), which passes through the base mount 27 and into the slab face 21, thereby securing the base 19 to the slab face 21. In installation, the adjacent slab face 21 is pre-treated prior to the base 19 being secured. For example, the slab face 21 may be sandblasted or otherwise abraded. The base 19 is then secured with screws 29. Preferably, the base 19 is also glued to the adjacent slab face 21.

Still referring to FIG. 1( a), the slab edge casing 11 further comprises a brace mount 49, which is positioned on one of the inside surfaces 23 of the casing 11. The reinforcing element 31 also further comprises an anchor brace mount 51, such as a suspender. With the casing 11 and reinforcing element 31 being configured with respective brace mounts (49, 51), the finished slab edge 10 additionally comprises a brace 53. The brace 53 extends between the reinforcing element brace mount 51 and the casing brace mount 49, and is connectable to the respective mounts 49, 51.

Preferably, the slab edge casing 11 comprises a second brace mount 55, also positioned on one of the inside surfaces 23, but, separate and apart from the first brace mount 49. The second brace mount 55 is connectable to a second brace 57, which extends from the reinforcing element 31. As will be apparent, the casing brace mounts 49, 55 may alternately be configured to function as additional casing ribs 39.

Still referring to FIG. 1( a), the braces 53, 57 may be wire elements, as is illustrated. As such, the respective brace mounts 49, 51 and 55 are configured to receive the wire elements, which are then secured to the mounts 49, 51 and 55. The wire elements may be secured to the mounts 49, 51 and 55 by any known means.

Referring to FIG. 4, an alternate embodiment of the brace 53 is illustrated. In this alternate embodiment, the brace 53 is a bar element, which may be composed of light gauge steel or a glass fibre reinforced polymer. As will be apparent, the brace 53 may be comprised of any material that suits the slab edge's particular installation environment.

In this alternate embodiment, the mounts 49, 51 are configured to receive the bar element. For example, as is illustrated in FIG. 4, the brace 53 may be shaped to engage the inside surface 23, thereby permitting the brace 53 to be secured directly to the inside surface 23. In this particular embodiment, the casing brace mount 49 is may be a rivet (or similar securing means) which secures the brace 53 to the casing 11. The opposite end of the brace 53 may be secured directly to the reinforcing element 31. In the embodiment illustrated, the brace 53 is secured in place between the anchor bolt 33 and the coupler 37. The brace 53 may be secured to the reinforcing element 31 and the casing 11 by any suitable means known to those skilled in the art.

The casing 11, as has been described above, is preferably composed of a GFRP. In an alternate embodiment, the casing 11 may be composed of a PVC (polyvinyl chloride). The thickness of the PVC composed casing 11 compared to that of the GFRP composed casing 11 will preferably be adjusted (increased) to compensate to PVC's relatively lower modulus of elasticity. In either case, respective thicknesses of the GFRP and PVC casings 11 will be selected, taking in to account the materials' respective modulus of elasticity, to minimise any deflection of the casing 11 caused by the concrete. Deflection is kept at a minimum in order to maintain the visual presentation of the finished slab edge 15.

PVC, as a material for casing 11 construction, offers a number of advantages over GFRP. One advantage is that PVC can be welded on site (in addition to being glued or cemented, as may also be required). Welding permits on site customization of the casing 11. It also reduces the number of welding plates that are required to connect casing pieces together, as in the corner portion of the finished slab edge, for example. An additional advantage of using PVC is that the face 13 and base 19 may be formed separately and welded on site to form the casing 11.

An embodiment of the present invention may alternately be characterized as a kit for finishing as unfinished slab edge. The kit comprises the casing 11, the reinforcing element 31 and a brace 53, as defined above, including the alternate embodiments. Preferably, the kit comprises a plurality of reinforcing elements 31 and a plurality of braces 53. For example, the kit may comprise an equal number of reinforcing elements 31 and braces 53.

Referring to FIG. 5( a), a corner portion of a finished slab edge 10 is illustrated in plan view. A slab edge corner casing 71 for the corner portion is illustrated. In the illustrated embodiment, the corner portion comprises two adjacent unfinished slab edges 17, which are positioned orthogonally to each other. Any suitable non-orthogonal positioning may be employed, as may be dictated by the slab structure.

The corner casing 71 comprises adjacent faces 13, which define the finished slab edge 10. From each face 13, a respective base 19 extends. The bases 19 are either connectable to a slab face 21 adjacent the unfinished slab edge 17; or, registerable with the unfinished slab edge 17. The faces 13 and bases 19 have respective inside surfaces which define a form unto which concrete is poured and allowed to cure. Each face 13, base 19 pairing also comprises a reinforcing element mount 25 for receiving a respective reinforcing element 31 that extends from the unfinished slab edge 17. As stated previously, the casing 13 may further comprise base mounts 27 (not shown) for receiving securing means, such as self-tapping screws 29.

Also, as stated previously, the corner casing 71 may further comprise a brace mount 49 positioned on one of the inside surfaces 23 (not shown). The brace mount 49 is connectable to a brace 53 extending from the reinforcing element 31 (not shown). The corner casing 71 may additionally comprise a second brace mount 55 (not shown). As will be apparent, the corner casing 71 is comprised similarly to the casing 11. As such, it may comprise:

a plurality of ribs 39 extending from the inside surfaces 23 (not shown); and,

a polymer composition, preferably a glass-fibre reinforced polymer.

As with the casing 11, the face 13 of the corner casing 71 has a length corresponding to the slab height. Alternatively, the face 13 of the corner casing 71 may comprise the first face portion 41 and second face portion 43, as described above.

Referring to FIG. 5( b), the corner portion of FIG. 5( a) is illustrated with the reinforcing element 31 comprising the rod 77. This corner portion is identical to that of FIG. 5( a) in all other respects.

Referring to FIG. 6( a), a corner of a finished slab edge 10 is illustrated according to an alternate embodiment. In this embodiment, the casings 11 are cut at an angle A, which is determined by the particular installation requirements.

Referring to FIG. 6( b), the corner portion of FIG. 6( a) is illustrated with the reinforcing element 31 comprising the rod 77. This corner portion is identical to that of FIG. 6( a) in all other respects.

Referring to FIGS. 5 and 6, means for connecting adjacent casings 11 (or 11 and 71) is illustrated. The adjacent casings 11 (or 11 and 71) are placed side by side. A coupling plate 73 is the positioned at the common border of the adjacent casings 11 (or 11 and 71). The plate 73 is then secured to the casings 11 (or 11 and 71), as is illustrated. Preferably, the connection comprises a base coupling plate and a face coupling plate. The plates 73 preferably are composed of a glass-fibre reinforced polymer.

Referring to FIG. 1( a), the finished slab edge 10 may further comprise reinforcing bars 59, which are positionable between the finished and unfinished slab edges 15, 17 in an orientation orthogonal to a longitudinal axis 61 of the reinforcing element 31. The reinforcing bars may be composed of any suitable corrosion resistant material, such as any one of glass-fibre reinforced polymer, carbon-fibre reinforced polymer, and steel (such as stainless steel).
